The keyboard is in bad condition, it seems that it comes in contact with water or used to be in a wet storage. The metal plate is rusty, the printed circuit board has some paths and areas oxidized, maybe even interrupted.
But despite some damage, I think this keyboard is still worth and could work again after desoldering and cleaning of switches and repairing of some broken paths because of its remarkable design. It will take lot of time and effort, but you will get unique keyboard.
I cleaned the keyboard as much possible, except the switches (only several).
Keyboard is tested and it works at 95%

The pros:
- rare and collectible keyboard
- with built in calculator
- lot of SKCM switches
- doubleshotted caps
- black color which is not so common
The cons:
- caps F7, F8 and F11 - don't work, I tried to connect the soldered pins and nothing...., seem to be some problem with the path on the board...
- original cap F5 is missing, another Alps compatible cap added
- calculator display - in very bad condition, shows only fragments (problem to get a new display)
- weaker contacts on several keys - R, G, booth ALT, &7, /?, big ENTER works only with connecting the soldered pins (oxidized inside switch), left arrow
- the whole section below the calc - it seems that it works (react) only with calc on, but during the first test, I think I managed to test the caps in test program, but later, it does not happen again
- scratches on the caps
- switches need to be cleaned with some "contactol" spray
- rusty metal plate and oxidized printed circuit plate
